SPECIFICATION forming part of Letters Patent No. 554,088, dated February 4, 1896. Application filed July 13,1894. Serial No. 517,485. (No model.)

To all whmn it may concern.-

Be it known that we, FRANQOIS XAVIER PAYMENT, a subject of the Queen of Great Britain, and JOHN C. HARTIG, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have inventeda new and useful Improvement in IVindow- Frames, of which the following is a specification.

Our invention relates to window frames or casings, and has for its object particularly to provide a window frame or casing so constructed that the window-sash can be easily removed and replaced and without injury to the casing or frame. It is illustrated in the accompanying drawings, wherein- Figure 1 is a vertical section of a frame, showing the parts in their ordinary positions in full lines and in dotted lines showing the positions the several parts may assume when the sash are to be removed or inserted. Fig. 2 is a vertical section on the line 2 2, and Fig. 3 is a detail of the locking device of the movable securing-rib.

Like parts are indicated by the same letters throughout the several figures.

A is the top, and C the sides, of the window frame or casing.

D is the exterior rib, Ethe interior rib and F the intermediate rib, whereby the sides of the frames are divided into two vertical sections or ways C 0 in which the sash move.

C is the lower inner sash and C the upper outer sash, and any suitable means for hold-' ing them in any desired position along the ways in which they run may be employed; but as this forms no part of our invention we do not here illustrate it.

In windows as ordinarily formed the ribs E and F are continuous from top to bottom of the casing, the rib F being ordinarily sunk into a groove, the strip or rib E being secured upon the side of the casing.

In our invention I-I illustrates the uppe movable portion of the rib E, the two coming together in a line H, and the upper portion H is slotted at J to receive the securing-screw J and yet permit a certain amount of verti cal motion in the part H. K is a similar movable upper portion of the rib F, joining the rib at the line K.

This section K is inserted I in a groove K. This groove instead of being the same depth throughout its entire length is of varying depth,increasing gradually from zero at the upper end of the window-frame to its full depth at the lower end of the strip K. As shown in the drawings, this is accomplished by inserting within such groove a beveled strip K The section K has its inner side beveled so as to fit the beveled surface of said strip. By this arrangement the upper end of the part K is flush with the side of the casing. Said part K is secured to the casing by means of a screw K which passes through the slot K Said slot is made larger than the screw K so that there may be a certain amount of longitudinal motion of the part K, in order that it maybe removed from the groove K when desired. A short rotatable shaft passes through the part H and is provided with a thumb-piece L, by which it may be controlled. The inner end of said shaft is grooved, as shown, and engages a rack L fastened to the frame of the window. By this construction the piece H may be locked in position and can be released by simply turning the thumb-piece L. As shown in the drawings, said interlocking portions consist of a thumb-piece L provided with a short rod that passes through the strip H, said rod having at its inner end a number of teeth that engage a rack L attached to the side of the window-frame. (See Fig. 3.)

The use and operation of our invention are as follows: The window being equipped as indicated and the parts being in position indicated in full lines, the effect is substantially that of an ordinary window. The upper sash is kept in any desired position from movement into or out of the room by the upper movable portion of the rib, which rests in its groove. On the other hand the inner sash is kept from a like motion by the upper movable part by reason of the interlocking portions which prevent such movable part from moving out ward, it being necessary to give it the downward and outward motion to disengage the locking parts. When it is desired to remove the lower or inner sash, the part II is swung inwardly, as indicated in dotted lines, and to permit it to turn at its upper end the slot is provided. The inner sash can then be lifted ISO to its highest position and moved out under the movable portion. If it is then desirable to remove the upper or outer sash, the movable section K is lifted out of the groove in the frame at its lower end and then brought around in the position shown in dotted lines, whereupon the upper sash can be removed, passing under the two movable portions.

\Ve claim 1. In a window-frame containing side ways in which the sashes are adapted to move, a rib in combination with a groove of varying depth in the frame, said rib secured at one end so that its lower edge is flush with the side of the casing and normally seated in said groove and adapted to be removed therefrom.

2. A window-frame comprising side ways for the vertical motion of the sashes, two-part ribs between the sashes located in grooves of varying depth in the frame, the upper parts of said ribs being attached at one end to the frame so that their lower edges are flush with the side of said frame, the other ends of such upper parts being removably seated in the groove in said frame, two-part inner strips attached to said frame, the upper part of such strips being connected to the window-frame so that said upper parts maybe moved longitudinally and to a position at an angle with the frame, whereby the window-sashes may be removed and replaced.

3. A Window-frame comprising side ways for the vertical motion of the sashes, two-part ribs between the sashes located in grooves of varying depth in the frame, the upper part of said ribs being attached at one end to the frame in such a manner that they may have a limited longitudinal motion, their lower edges at the end they are connected to the frame being flush with the side of said frame, the other ends of said upper parts being removably seated in the grooves in said frame, so that they are normally securely held in place, two-part inner strips adapted to be moved to an angular position and attached to said frame, so that they will have a limited longitudinal motion, a rotatable shaft passing through the lower ends of each of said latter strips, and a rack connected with the windowframe and adapted to be engaged by said shafts so as to lock said strips in position.
